[Wien] a problem about optic property with spin-orbital coupling

[line_shi@163.com]

 Dear wien users:
 
  In my calculation(no spin) of optic property i encountered a problem as follow:
i can successfully do optic calculation without spin-orbital coupling,
but when i take into account spin-orbital coupling the case.symmat file is full of NAN(Not a Number) symbol. Who can tell me what's wrong with my calculation?
 
   I did my calculation as follows:
1. self-consistent calculation
2. spin-orbital coupling calculation
3. creat a dense k-point file
4. change TOT to FERMI in case.in2c
5. run_lapw -so -e lapw1 -s lcore
6. x opticc -so
 
 
Thank you very much for your help!
